                                Figure of an otocousticon (a trumpet for hearing) by Thomas Mace (1612/13-c. 1709). Mace was at Trinity College, Cambridge, and an accomplished lutanist (despite being deaf) and author of Music's Monument (1676). The instrument is described by Isaac Newton in a letter dated 30 November 1675 to Henry Oldenburg.
There is an earlier sketch of a similar instrument by John Wallis in 1668 (EL/W1/63/001).
There are copies of this figure at LBO/7/279 and LBC/7/422.
